| 摘 要： | 用泵浦能量具有梯度分布的横向同步泵浦方案,产生超短行波自发辐射光脉冲。以N_2激光为泵浦源,获得约50ps的染料光脉冲输出,以锁模Nd:YAG倍频光作泵浦源,获得8～15ps光脉冲。用条纹照相机和光学多道分析器测量了脉冲波形和光谱。 计算机模拟了行波放大自发辐射的瞬态行为,计算结果与实验结果相符合。

Investigation of ultrashort travelling wave amplified spontaneous emission |
| |
| Abstract: | Ultrashort travelling wave amplified spontaneous. emission(A8B)is generated by transversal synchronizing pumping scheme with gradient distribution of pumping energy. 50 ps light pulses are generated by nitrogen laser pumping and 8 to 15 ps pulses generated by frequency doubled and mode-looked Nd:YAG laser pumping. The pulse shape and spectrum of the travelling wave ASE as well as the non-travelling wave ASE are measured by means of streak camera and optical multichannel analyzer. The computer simulation on the temporal behaviour of the travelling wave ASE is pressented and the calculation is in good agreement with the experimental results. |
